Design and Simulation of E-Slot Patch Antenna with Coaxial Feed for Multi Band Applications

Abstract

The main object of this paper is to design and to simulate micro strip slot patch antenna for multiband applications. It is omnidirectional and stable radiation pattern. Hence rectangular shape antenna can be simulated using ANSOFT HFSS software. Parameters such as return loss, VSWR and radiation pattern are taken. Micro strip slot patch antenna becomes very popular day to day because of easy analysis and fabrication, low cost, light weight, easy fabrication. This paper proposed some shapes using feeding techniques are which has effective transmission based on frequencies. Micro strip patch antennas offer an attractive solution compact, conformal and low cost design of many wireless application systems. By increasing the substrate thickness and decreasing the permittivity of substrate the percentage of band width is increased. HFSS software is used for simulation and design of micro strip patch antenna where its version is 11.0. HFSS means High Frequency Structure simulator this was launched by the ANSOFT, designs are four slot patch antennas and the antennas work in the frequency ranges as follows 4.15-4.39 GHz, 10-11.6 GHz, 13.2-14.3 GHz, 16-17.1 GHz, 19.1-20 GHz, 4.4-4.5 GHz, 8.7-9.1 GHz, 11.54-12.85 GHz, 1.65 GHz, 2.24 GHz, 4.4-4.6 GHz, 5.6- 5.8 GHz, 7.45-8.15 GHz It’s main objective is used for MIMO applications, WLAN, Wi-MAX and RADAR, UWB, mobile communications, satellite space communications and microwave frequencies.
